Here, our work is also an encoder-based method [rgb]0,0,0and work in an online fine-grained manner, but [rgb]0,0, 0we use the learned pseudo labels to optimize our feature encoder \(E_{SGA}\)  rather than using video-level labels as pseudo labels directly. Moreover, we design a two-stage self-training scheme to efficiently optimize our feature encoder and pseudo label generator instead of iterative optimization[1]}.
